MEANS FOR PREVENTING'LONGITUDINAL MOVEMENT Ol' RAILS 0F RAlLROADS.

SPECIFICATION forming part of Letters Patent No. 437,301, dated September 30, 1890. Application filed May 22,1890. SerialNo. 352,797. (Nomodeh) To all whom it may concern.-

Be it known that I, FRANK G. JOHNSON, a citizen of the United States, residing in the city, county, and State of New York, have invented a new and useful Improvement in Means for Preventing the Longitudinal Movement of Rails of Railroads, which movement is popularly termed creeping of rails, of which the following is a specification.

Referring to Letters Patent No. 354,1i7, granted to me December 14, 1886, for improvements in steel ties it will be found that the clip for holding the rails is prevented from moving in the lateral direction to the line of the rail by a post at its outer end extending down through a corresponding hole in the top of the tie. The other or inner end of the said clip is prevented from moving in the direction of the line of the rail by the bolt which clamps the clip, rail, and tie together, for the reason that the width of the oblong hole in the top of the tie is the same as the diameter of the clamping-bolt, and the rail is prevented from rising from the tie by the said bolt. Hence this said clip positively holds the rail to the tie in the lateral and vertical directions, but not necessarily in the longitudinal direction to the rail. Therefore the object of my present invention is to improve this said clip and so modify the rails as to also positively and immovably hold the rails to the ties in the longitudinal direction to the road, which objectl attain by the mech anism illustrated in the accompanying drawings, in which Figure 1 is a vertical section on the line a 00 of Fig. 2, showing the connection between the clip above alluded to as improved and the rail as modified to conform to this improved clip; Fig. 2, a plan view, the line as a corresponding to the line y y of Fig. 1; Fig. 3, a View of the clip from the lower side; Fig. 4, a vertical section of a modification of my device; Fig. 5, an under side view of the clip as thus modified.

Similar letters refer to similar throughout the several views.

Arepresents the rail; B, the steel tie; C, the clip; D, the post of the clip, that passes parts through a corresponding hole in the top of the tie that holds the clip and rail in the lat eral direction; E, the nose of the clip, that projects over and bears upon the upper face of the base of the rail; F, the clamping-bolt that holds the clip, rail, and tie together in the vertical direction; a, an oval or nipplelike projection on the lower face of the nose E of the clip 0, which fits into the corresponding depression or socket 11. provided in the upper face of the base of the rail A. On the lower side of the clip C there is a shoulder e 6, Fig.3, at the outer termination of the nose E, that rests against the edge of the base of the rail.

Having thus briefly pointed out the several parts of my device, their operation whereby the desired result isattained is explained thus: The rail cannot rise or move vertically from the ties because the nose of the clip is helddown by the clamping-bolt F. It (the rail) cannot move laterally on the tie because the edge of the base of the rails rests against the shoulder e 6, Fig. 3, of the clip, and the clip in turn is held from moving because the post D passes down through the top of the tie, and the rail cannot creep on ties or move in a longitudinal direction without carrying the ties with it because the nipple n is securely held by the clamping-boltin the corresponding depression or socket a, the nose E of the clip, and consequently the nipple n, being held in the longitudinal direction of the rail by the clamping-bolt F fitting or being held by bearing against the sides of the oblong bolt-hole in the top of the tie. Hence it is evident that therail cannot move either vertically, laterally, or horizontally without carrying the tie with it.

The modification of my device, as shown in Figs. 4 and 5, shows a lug or projection on the lower side of the nose of the clip, which is made to fit in a corresponding notch cut entirely through the edge of the base of the rail but to this modification there is the se rious objection that these cut-through notches might cause a tendency of the rail to break at these points. Besides, there would be great difficulty in providing these notches in rails already laid, while they (the rails now in use) could be easily prepared for the nipple n by simply countersinking the oval depressions or sockets 'n to receive the nipple n and Without injury to the rails themselves.

It will be seen by my device that without appreciable cost the rail can be longitudinally (as well as otherwise) secured at the point of every tie, and be thus as firmly held from creeping as the resistance of the combined counteraction of the ties will afford. By means of my improvement thus set forth and the employment of amply strong clamping clip-bolts F there is no possibility of the rails moving in any direction without correspondingly moving" the ties-a result not heretofore attained.

Having described the several parts of my invention and pointed out their respective functions, what I claim as new and useful, and desire to secure by Letters Patent, is-

1. In connection with railroads, the clip 0, having the post D and the nipple 02, in comblnation with the rail A, having the depressions n n, as and for the purpose set forth. In connection with-railroads, the clip 0, having the post 1) and nipple oz, in combination with the clamping-bolt F and rail A, having the depressions n or, substantially in the manner and for the purpose described.

In connection with railroads, the clip 0, having the post D and nipple n, in combination with the rail A, having the depressions n n, clamping-bolt F, and tie l3, substantially in the manner and for the purpose described.
